Thus, the sealing performance of the brewing mechanism 2 can be enhanced to prevent the liquid and powders in the beverage capsule from splashing out, thereby further reducing the cleaning difficulty of the brewing mechanism 2.
For example, referring to
According to some embodiments of the present disclosure, a side (e.g. a left side in
Specifically, a top of the grip portion 213 is higher than the brewing cover 22 by a distance U, and U satisfies 5 mm≤U≤10 mm. In some embodiments, U is 5 mm. Thus, the liquid can be effectively prevented from splashing, so as to further enhance the safety of the beverage machine 100. Additionally, the grip portion 213 constitutes a part of the overall appearance of the beverage machine 100, such that the whole beverage machine 100 is more aesthetic and materials are saved, thereby reducing the material cost of the beverage machine 100.
Specifically, referring to
Specifically, the grip portion 213 and the brewing body 21 are integrally molded, the process is simple and has low cost.
According to some embodiments of the present disclosure, a distance Q between the central axis of the second piercing needle 222 and an outer side surface of the grip portion 213 satisfies 35 mm≤Q≤45 mm. In some embodiments, Q further satisfies Q=40 mm. A distance G between two ends of the grip portion 213 satisfies 75 mm≤G≤85 mm. In some embodiments, G further satisfies G=81 mm. Thus, the volume of the brewing mechanism 2 can be decreased, and the overall volume of the beverage machine 100 can be reduced, thereby saving the space occupied by the beverage machine 100 (like the coffee machine).
Specifically, a distance V between two ends of the brewing body 21 connected to the grip portion 213 satisfies 62 mm≤V≤70 mm. In some embodiments, V further satisfies V=65 mm. Thus, the volume of the brewing body 21 can be further reduced.
According to some embodiments of the present disclosure, referring to
Specifically, the machine nose 11 and the base 13 are connected to the main body 12 through the frame 4 separately. Optionally, the machine nose 11 and the base 13 can be connected to the frame 4 through screws or snaps 46. For example, referring to
For example, during the assembly, the frame 4 can be connected to the base 13 first through the fitting between the second screw 492 and the second nut column 131, then the main body 12 is fitted over the frame 4, and finally, the machine nose 11 is connected to the frame 4 through the fitting between the first screw and the first nut column 491. Thus, the main body 12 can be limited between the base 13 and the machine nose 11, such that the base 13 and the main body 12 can be fastened into a whole through the frame 4, the structure is simple, and the assembly is convenient.
According to some embodiments of the present disclosure, a distance L1 between a lower end face of the brewing mechanism 2 and an upper surface of the base 13 satisfies 110 mm≤L1≤180 mm. Specifically, referring to
According to some embodiments of the present disclosure, referring to
Specifically, the main body 12 is formed in a cylindrical shape, an outer diameter of the main body 12 is D that satisfies 125 mm≤D≤140 mm, and a specific value of D can be determined in the light of practical requirements. For example, D can further satisfy D=130 mm. Thus, the overall volume of the beverage machine 100 can be further decreased.
According to some embodiments of the present disclosure, a height H of the machine body 1 satisfies 230 mm≤H≤295 mm. In some embodiments, H further satisfies H=235 mm. Thus, the appearance of the beverage machine 100 can become more aesthetic.
Specifically, a length L3 of the machine body 1 satisfies 225 mm≤L3≤240 mm. For example, L3 can further satisfy L3=230 mm.
A brewing method for a beverage machine 100 according to embodiments of a second aspect of the present disclosure includes steps: putting a beverage capsule into a brewing cavity 24; closing a brewing cover 22 and piercing a top of the beverage capsule first by a second piercing needle 222 of the brewing cover 22; piercing a bottom of the beverage capsule by a first piercing needle 231 of a needle disc 23; pushing a brewing mechanism 2 into the beverage machine 100, and detecting, by the beverage machine 100, whether the brewing mechanism 2 is installed in place. Thus, the way of piercing is effortless, and the beverage capsule is easy to pierce; the beverage machine 100 can be started only when the brewing mechanism 2 is installed in place, thereby ensuring the safety of the beverage machine 100.
Referring to
For example, during brewage of a beverage (like coffee), when the liquid level sensor senses that the liquid level in the boiler 1 reaches the water level (e.g. the minimum liquid level line) detected by the liquid level sensor, time counting to t2 is started. Therefore, it can be ensured that when a different amount of liquid is added into the brewing cavity 24, the time of air extraction of the liquid pump 5 keeps consistent, thereby guaranteeing that residual liquid in the brewing cavity 24 can be blow-dried and reducing the cleaning difficulty of the brewing cavity 24; additionally, residual beverage in the brewing cavity 24 can be prevented from dripping around when the brewing mechanism 2 is taken out, which otherwise may contaminate the ambient environment.
According to some embodiments of the present disclosure, t2 satisfies 20 s≤t2≤30 s. For example, t2 can further satisfy t2=30 s. Thus, it can be ensured that the residual liquid in the brewing cavity 24 is blow-dried.
Further, the boiler 3 heats the liquid in the boiler 3 through a heating device 7, such as a heat radiating tube and a heating tube. After the heating device 7 heats the liquid in the boiler 3 up to the preset temperature, the heating device 7 stops working, and after a first preset time, the liquid pump 5 is started. Specifically, the first preset time is tl, and the first preset time tl satisfies 5 s≤t1≤10 s. In some embodiments, tl further satisfies t1=5 s.
For example, during the beverage (e.g. coffee) brewage, the heating device 7, for example the heat radiating tube, can be first started to heat the liquid (e.g. water) in the boiler 3. When the liquid (e.g. water) in the boiler 3 reaches the preset temperature, the heating device 7 stops working, and after the first preset time, the liquid pump 5 is started. In this case, during the first preset time, remaining heat of the heating device 7 (e.g. the heat radiating tube) can be used, i.e. make use of the remaining heat of the heating device 7 to heat the liquid in the boiler 3, so as to keep the temperature of the liquid (e.g. water) stable, thus making a temperature for the beverage brewage stable, and ensuring the taste of the beverage (like coffee). Additionally, energy is greatly saved, thereby avoiding energy waste.
The preset temperature is T, and T satisfies 80° C.≤T≤90° C. For example, the temperature of the liquid in the boiler 3 can be monitored by a thermistor 33 on the boiler 3. Thus, it is possible to improve the taste of the beverage and satisfy the user's requirement for the quality of the beverage.
According to some embodiments of the present disclosure, the working time of the heating device 7 is t3, and t3 satisfies t3≤120 s. In this case, a timer can be provided in the beverage machine 100, and when the thermistor 33 or other temperature measurers fails or produces a large error, it is possible to avoid overheating the boiler 3 by means of the timer, so as to shorten the entire time for the beverage brewage. Additionally, the safety hazard is further reduced, and the safety of the beverage machine 100 is enhanced.
According to some embodiments of the present disclosure, the method for controlling the beverage machine 100 further includes the following steps: controlling the beverage machine 100 to be powered off when the liquid in the boiler 3 reaches the preset temperature T; or controlling the beverage machine 100 to be powered off by means of a snap-action thermostat 38, when the thermistor 33 fails and the temperature of the boiler 3 reaches a temperature point of the snap-action thermostat 38; or controlling the beverage machine 100 to be powered off, when the thermistor 33 and the snap-action thermostat 38 both fail, and the timer starts counting from the time of heating and counts to t5. Therefore, the beverage machine 100 can be triply protected by the thermistor 33, the snap-action thermostat 38 and the timer, thereby reducing the safety hazard and guaranteeing the operation safety of the beverage machine 100 considerably.
Specifically, t5 satisfies 120 s≤t5≤180 s. Thus, it is possible to lower the safety hazard and improve the safety of the beverage machine 100.
Further, before the step of starting the heating device 7, the method also includes: detecting whether the liquid level in the boiler 3 reaches a preset liquid level. For example, the liquid level in the boiler 3 can be detected by the liquid level sensor (e.g. a liquid level sensing rod). Thus, it is convenient to monitor whether the liquid in the boiler 3 meets the requirements for brewing the beverage, thereby effectively improving the taste of the beverage.
According to some embodiments of the present disclosure, before the step of starting the heating device 7, the method also includes: detecting whether the brewing mechanism 2 is installed in place. It is preferable to detect whether the liquid level in the boiler 3 reaches the preset liquid level after detecting whether the brewing mechanism 2 is installed in place.
Further, the beverage machine 100 further includes a working status indicator lamp (not illustrated), and when the beverage machine 100 is in an abnormal status, the working status indicator lamp flickers rapidly. It should be noted herein that “the abnormal status” in the present application means the brewing mechanism 2 is not installed in place or the liquid level in the boiler 3 does not reach the preset liquid level.
For example, when the liquid level in the boiler 3 does not reach the preset liquid level line, the working status indicator lamp can be set to flicker rapidly, for example regularly flicker rapidly at 200 ms (milliseconds), so as to remind the user to adjust the liquid level in the boiler 3. Hence, it is convenient to monitor whether the liquid in the boiler 3 meets the requirements for brewing the beverage, thereby effectively improving the taste of the beverage.
Moreover, the brewing mechanism 2 can be provided with a safety switch 112. For example, when the brewing mechanism 2 is installed in place, the safety switch 112 can be triggered, the brewing mechanism 2 is powered on, and hence the beverage (e.g. coffee) brewage can be continued. When the brewing mechanism 2 deviates from the correct position, an error message can be provided, and for example, the working status indicator lamp can be set to regularly flicker rapidly at 200 ms (milliseconds), so as to remind the user to adjust the position of the brewing mechanism 2. Therefore, the beverage machine 100 can be prevented from working in the case where the brewing mechanism 2 is deviated, so as to reduce the safety hazard effectively and further improve the safety and reliability of the beverage machine 100.
Specifically, the time required for the liquid pump 5 to convey all the liquid in the boiler 3 to the brewing cavity 24 is t4, and t4 satisfies 35 s≤t4≤60 s. Thus, not only the liquid amount requirement of the beverage brewage can be satisfied, but also the entire time for the beverage brewage can be shortened.
A specific embodiment of the method for controlling the beverage machine 100 according to the present disclosure will be described below with reference to
The method for controlling the beverage machine 100 according to the embodiment of the present disclosure includes the following steps: detecting whether a brewing mechanism 2 is installed in place; detecting whether the liquid level in the boiler 3 reaches the preset liquid level; starting the heating device 7 to heat the liquid in the boiler 3; detecting whether the liquid in the boiler 3 reaches the preset temperature or whether the working time of the heating device 7 reaches 120 s; when the liquid in the boiler 3 reaches the preset temperature or the working time of the heating device 7 reaches 120 s, stopping the heating device 7, and starting the liquid pump 5 after 5 seconds; and when the liquid level in the boiler 3 reaches the minimum liquid level line, the liquid pump 5 continues working for 30 seconds.
Specifically, during the coffee brewage, a boiler cover 113 is opened first, and the boiler cover 113 is closed after an appropriate amount of water is added into the boiler 3; then, a brewing cover 22 is opened, and after a coffee capsule is put into the brewing cavity 24, the brewing cover 22 is pressed; a second piercing needle 222 of the brewing cover 22 first pierces a top of the coffee capsule, and then a first piercing needle 231 in the brewing cavity 24 pierces a bottom of the coffee capsule; the brewing mechanism 2 is connected to a machine nose 11, and a coffee machine is connected to a power source, in which case an indicator lamp on the coffee machine is on, and the coffee machine enters a standby status.
A start switch of the beverage machine 100 is pressed; the brewing mechanism 2 is detected whether it is installed in place; when the position of the brewing mechanism 2 is wrong, the working status indicator lamp regularly flickers rapidly at 200 ms (milliseconds) to remind the user to adjust the position of the brewing mechanism 2, until the brewing mechanism 2 is installed in place; the liquid level in the boiler 3 is detected whether it reaches the preset liquid level.
When the liquid level in the boiler 3 does not reach the preset liquid level line, the working status indicator lamp regularly flickers rapidly at 200 ms (milliseconds) to remind the user to adjust the liquid level in the boiler 3, until the liquid level in the boiler 3 reaches the preset liquid level, and then the heat radiating tube is started to heat the water in the boiler 3.
When the water in the boiler 3 reaches 80° C., or the working time of the heat radiating tube reaches 90 s, the heat radiating tube stops working, and the liquid pump 5 is started after 5 seconds. After the water level in the boiler 3 reaches the minimum liquid level, the liquid pump 5 continues working for 30 seconds.
With the method for controlling the beverage machine 100 according to embodiments of the present disclosure, the remaining heat of the heating device 7 is fully utilized, thereby saving energy considerably and reducing the energy consumption of the beverage machine 100. Additionally, the safety and reliability of the beverage machine 100 is enhanced.
